HYDRAULIC OIL-TAN K.

SPECIFICATION forming part of Letters Patent No. 727,779, dated May 12, 1903.

Application filed October 31, 1902. Serial No. 129,519. (No model.)

To all whom it may concern.-

. Be it known that I, ALBERT O. FRIESEKE, a citizen of the United States, residing at Floralbluif,county of Duval,and State of Florida,

air, and I also provide means for drawing the oil from the tank by one pressure.

Other minor objects will be set forth more clearly in the specification.

With these ends in view this invention consists in the details of construction and com-- bination of elements hereinafterset forth and then specifically designated by the claims.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, the construction and operation will now be described in. detail, referring to the accompanying drawings, forming a part of this specification, in

the opening A, so as to make the tank airtight.

whichi a I Figure 1 is a vertical longitudinal section through my improved oil-tank, showing the parts in the position they would assume when oil is being drawn from the barrel into the tank; Fig. 2, a vertical longitudinal section through the tank, showing the same entirely filled with water; and Fig. 3, a sectionalview. of the plug to be inserted in the top of the tank.

A represents the oil-tank, which is entirely closed except for the small opening A through Interposed in the pipe D is a two-way valve D, from which thespout F leads.

G is a rod secured at its lower bottom of the tank.

G is a float the specific gravity of which is such that it will float upon water, but not upon oil. Extending through and secured to the center of this fioat is a sleeve G which surrounds and slides upon the rod G, whereby the float is guided.

The supply-pipe B is provided with a valve B, the valve-stem of which is connected, by means of'a rod B with a lever D which lever is secured to the stem of the two-way end to the The outlet-pipe C is provided with anopening through its upper side upon the interior of the tank, and this opening is adapted to be controlled by a flap-valve O, to which a float C is attached, so that this valve will remain normally open.

O is a valve located in the pipe 0 outside of v the tank, the valve-stem C of which extends up to the upper end of the tank and is adapted to be turned by means of the handle C H is a screw-plug adapted to be inserted in B opened. Water will then enter the tank,

andas the water rises in the tank the float G will rise with it, and when the sleeve Gr protrudes through the opening A the valve Bis closed; Then one endof the siphonpipe Iis inserted in the opening A, so as to make anflair-tight counectionwith the tank, and-the other end of the pipe I is inserted in the barrel of oil. Then the valve 0 is opened,

and the water will flow out of the tank through the pipe 0, and in so doing will draw theqoil from the barrel into the tank, and as the float G will follow, the water-line downward-when it reaches nearly to the bottom of the tank it v moving the pipe I, and inserting the screwplug H the tank is filled with oil and has not been and is not exposed to the air, so that no evaporation will ensue.

The plug of the valve D is provided with a straight passage D and also with a passage D at right angles to the passage D extending from one side of the plug to the passage D The valves D and B by being connected together by the connection B may be operated by one handle J, and when the valve D is turned so that the passage D is vertical and the opening to the spout Fis closed then the valve B will be open, and the water entering the tank underneath the oil will thus force the oil upward into the measuring vessel E, and when sufficient oil has been admitted to the vessel E the plug of the valve D is given one-quarter of a revolution, which will bring it in the position shown in Fig. 2, closing the valve B and allowing the oil to flow from the vessel E through the spout F into the proper receptacle. Thus as the oil is drawn from the tank the water will gradually rise in the same, carrying the float G upward with it until the sleeve G will protrude through the opening A when the plug is removed, and thus indicate that the supply of oil in the tank has been exhausted. Of course it will be understood that the plug is only removed temporarily to ascertain if the oil is nearly exhausted, and when this plug is removed no pressure will be upon the oil, as the water will be shut off, and when the plug is reinserted it will press the float and sleeve downward.

L is a tapering adjustable nozzle adapted to fit over the lower end of the spout F, and this nozzle carries a spring L, the free end of which is in partial contact with the spout, so that this nozzle may be raised or lowered to suit different heights of receptacles, but always remain upon the spout.

The advantage of my improved tank is that the contents are hermetically sealed, rendering waste from evaporation and accidents resulting therefrom impossible, the oil not being exposed to air while transferring it from the barrel to the tank, and even while transferring oil from the measuring vessel to the purchasers receptacle it is never exposed to the outer air.

Another advantage of my improved tank is that no space is left in the tank in which gas may form, the tank being always filled with either water or oil, or both, and thus manyaccidents are avoided,which result from partially-filled tanks of inflammable fluid in which a large gas-space is formed and the gas may become ignited by various causes.

Another advantage of my tank is that no labor is required to operate the same, as the tank is filled and emptied hydraulically, and therefore no pu m pin g is required, and by utilizing this water-power I am enabled to simplify the construction greatly, and by forcing the oil upward into the measuring vessel by means of water I am enabled to always make an accurate measurement and must always be uniform, which fact is evident to the eye of the purchaser.

Having thus fully described my invention, what I claim as new and useful is-- 1. In an oil-tank, a reservoir provided with a small opening through its upper end, a removable plug adapted to normally close saidopening, a water-supply pipe entering the reservoir near its lower end, a valve located in said pipe, an outlet-pipe extending through the lower end of the reservoir, said pipe provided with an opening into the interior of the reservoir, a float-valve adapted to controlsaid opening, a valve located in the outlet-pipe outside of the reservoir, a float of such specific gravity as to float in water and not in oil arranged upon the interior of the tank and guided vertically therein, a pipe extending upward from the upper end of the reservoir, a measuring vessel located upon the upper end of said pipe, a two-way valve located within said pipe, said two-way valve being connected to the valve in the inlet-pipe so that the two valves will operate together, a spout extending from the two-way valve, and a siphon-pipe, one end of which is adapted to be inserted in the opening in the reservoir, and the other end in an oil-barrel, as and for the purpose specified.

2. In a device of the character described, a tank, a water-supply pipe entering the lower end of said tank, a water-outlet pipe extending from the lower end of said tank, valves located within these pipes, an oil-outlet pipe extending from the upper end of the tank, a siphon-pipe by which the upper end of the tank is connected to an oil-barrel, a float guided vertically within the tank, said float being of such specific gravity as to float upon water and not upon oil, a valve arranged upon the inner end of the water-outlet pipe, said valve consisting of a flap normally open and adapted to be closed by the weight of the float, as and for the purpose specified.

3. In combination in a device of the char= acter described, a tank provided with a water inlet and outlet at its lower end, and an oiloutlet at its upper end through which the oil is expelled from the tank hydraulically, an opening through the upper end of the tank through which the oil is drawn hydraulically into the tank, a plug normally closing said opening, a valve located in the water-inlet pipe, and a valve located in the oil-outlet pipe, a connection between the valve-stems ofboth valves so as to cause them to work in unison,

a valve located upon the inner end of the water-outlet, a float adapted to float upon the water and not the oil, said float being guided so as to come in contact with the last-named valve and close the same by its weight, as specified.

4.. In a device of the character described, a

the same when said float is at its lowest'position, as specified.

In testimony whereofl have hereunto affixed my signature in the presence of two subscribing witnesses.

ALBERT G. FRIESEKE.
